Why is the brake pedal in the new Buick Regal so squishy?

I looked at new a Buick Regal and found its brake pedal to go right to the floor instead of being firm. I was told that the government mandated that this because they did not want people to stop suddenly when braking and that all cars will be this way from now on.. I find this hard to believe. The brakes felt very unsafe.

Any thoughts?
